Failure of any of these steps may occur due to unusual tooth morphology. Proper knowledge of root canal anatomy is a basic prerequisite for the endodontic treatment successful. Mandibular molars may have an additional root located lingually (radix entomolaris) or buccally (radix paramolaris). Awareness and understanding of the presence of unusual external and internal root canal morphology contributes to the successful outcome of the root canal treatment.

Local anesthetic, which forms the foundation for the delivery of pain-free endodontic treatment, does not serve the purpose in anxious patients and requires augmentation with other pharmacological agents. Aims: The aim of this study is to observe the effectiveness of nitrous oxide in alleviating patient anxiety and pain during endodontic treatment of a vital tooth. Settings and Design: The present in vivo study was conducted on sixty healthy patients from the Outpatient Department of Genesis Institute of Dental Sciences and Research, Ferozepur, Punjab, India. Subjects and Methods: Sixty anxious patients having irreversible pulpitis in their lower molar were selected and divided into two groups, namely control group and intervention group, with thirty patients placed in each group. In control group, access opening and pulp extirpation was done under local anesthesia only, whereas...

Materials and Methods: One hundred and fifty freshly extracted mandibular premolars were randomly divided into five experimental groups of 30 teeth each and biomechanical preparation was done: Group 1 with unprepared teeth; Group 2 were prepared with hand files; Group 3 with ProTaper rotary instruments; Group 4 with K3 rotary; Group 5 with Easy RaCe rotary instruments. Then, roots were cut horizontally at 3, 6, and 9 mm from apex and were viewed under stereomicroscope. The presence of dentinal defects was noted. Statistical analysis: Groups were analyzed with the Chi-square test. Results: Significant difference was seen between groups. No defects were found in unprepared roots and those prepared with hand files. ProTaper, K3 rotary, and Easy RaCe preparations resulted in dentinal defects in 23.3%, 10%, and 16.7% of teeth, respectively. More defects were shown in coronal and middle sections, and no defect was seen in apical third. Conclusion: The present study revealed that use of rotary instruments could result in an increased chance for dentinal defects as compared to hand instrumentation.

Teeth most affected are maxillary lateral incisors and bilateral occurrence is not uncommon. The abnormal morphology of these teeth often produces infections of odontogenic origin. The caries prone invagination of tooth structure which may communicate with the dental pulp leads to early necrosis with a resultant periapical infection. It is thus important that an early diagnosis of the presence of such teeth be made in order to avoid extraction at later stage. This case report describes the anomalous development of maxillary right and left permanent lateral incisors characteristic of dens invaginatus.

If present, an awareness and understanding of this unusual root and its root canal morphologycan contribute to the successful outcome of root canal treatment. This report discusses endodontic treatment of two mandibular molars with a radix entomolaris, which is rare macrostructures in the Caucasian population. The prevalence, the external morphological variations and internal anatomy of the radix entomolaris are described. Avoiding procedural errors during endodontic therapy demand an adapted clinical approach to diagnosis and root canal treatment.

Forty five permanent mandibular molars were selected and divided into three groups. In Group- A, Crown-down pressureless technique of root canal preparation was used. In Group-B, Double-flared and in Group-C conventional techniques were used to prepare root canals. Sealapex was used as a root canal sealer in all three groups. The treated teeth were examined clinically and radiologically after 1 month, 3 months, 6 months and 12 months. The percentage decrease in radiolucency after 12 months was 84.55 and 89.51 in Group-A, 74.80 and 84.33 in Group-B and 72.46 and 84.61 in Group-C. The findings of this study favours use of Crown-down pressureless technique while undertaking single visit root canal therapy.
